| Trouble with minimising the IDE. | In case one can not minimise the IDE, simply goto the mP icon on the taskbar and play a little but with "Restore" and "Minimize"to make minimisation of the IDE work again. Also editing the ShowCmd line in the settings.ini: set it to 1 instead of 2 may help. |
| Simple Touch Detector. | Tip from joseLB: This small code snippet is detecting touches. The circuit is just a PIC alone in EP3, pull ups off, and no matter board leds for port A are on or off. |
| Remote Control Repeater. | Tip from joseLB: Here is a TV, video, etc. remote control repeater Pascal code. It just get the signal arrived from up to 4 sources (4 places where you can put a TSOP receiver). |
| USB Switch. | Tip from joseLB: This is a very simple USB 2.0 switch. With it you can switch a USB device betwen 2 PC's. Tested with penDrives of 1,2,4,16Gb, Vista, XP, USB1.0, USB 2.0. |
| 20KWatts AC swithing. | Tip from joseLB: The need was needing to switch on/off trifasic power up to 30Amps/phase, 220V~ = ~11KVA. Switching should be done even when there is no power supplied.... |
| 5V Switched Mode Power Supply. | In applications with e.g. a PIC, an SD/MMC card reader, an Ethernet interface based on the ENC28J60 and an RS232 interface based on the Max232, the current drawn from the 5V power stabiliser becomes rather high. A heat sink is required for the stabiliser IC (usually an 7805, fed from an transformer via a bridge rectifier and a buffer elco). Things get worse if more components are added to the circuit: the heatsink must become bigger and bigger. Of course one can take a number of mesures to make the input voltage of the 7805 as low as possible (but not too low: stabilisation must still be possible), but even then the dissipation problem persists. This circuit poses a solution to that problem. Details. |
| SPI problem and MicroChip | Do NOT try to use the "SS" pin (SPI Slave Select) as digital input or output while using the SPI master mode. In the MSSP engine there is (at least in some PIC's like the P18F2620) a silicon problem, making an SS pin change destroy SPI data. Solution: set the SS pin (RA5 in the P18F2620) to output and never change its value. |
| SD/MMC QuickFormat for more than 512 files | How to format an SD/MMC card in FAT 16 for more than 512 root directory entries. Since the mmc_Fat_... routines only make use of the root directory, all files must be in it. As the number of root directory entries in Fat16 is defined during formatting (and thus fixed during usage of the SD/MMC card) and set to 512 by "mmc_Fat_Quickformat", this can cause a problem. This piece of code allows to to format the card to have more than 512 entries/files in the root directory. |

| RS232 to PIC interface | RS232 interface based on discrete components. Only 1 RX and 1 TX line (but can be extended of course). The "positive" Rs232 voltage is only 5V, but for most PC's that is no problem. |
| Using Leds, Buttons and Relays | Tips about Leds, buttons and relays. |
| Creating multiple "software" timers in your program. | Sometimes a (high) number of different timed activities has to be performed, e.g. creation of timeouts for expected events. Since the number of timers in a PIC is limited, the trick is to use one hardware timer and derive a number of SW timers from it. Orher related items (more advanced) are : TimeBase, simple time measurement. and Cooperative Operating System. |
